Is the old Paris Hilton back?

The 35-year-old socialite returned to her runway days, walking in Philipp Plein's show during Milan Fashion Week on Wednesday.

Hilton hit the catwalk in a black strapless, cut-out gown that featured an intricate bodychain, which was paired with thigh-high gladiator sandals and metallic aviators.

Apparently the former reality star's life is so bright, she has to wear shades indoors. Not only that, but she was a clear fan of the rock star ensemble, captioning an Instagram collage on Thursday, "Last night was so much fun! Loved walking in@PhilippPleinInternational's runway show. His new collection is sick!!🔥💯 Those gladiator boots are everything! 😍."

Hilton's outfit wasn't even the craziest in Plein's Spring/Summer '17 collection, however -- her fellow models, including Karolina Kurkova, also rocked some bold black numbers.

The show was a straight-up party and the place to be in Milan. Not only did Hilton get back to her modeling roots, Fergie and Fat Joe performed.

Plein titled his show Alice in Ghetttoland, and the stage truly was a wonderland of fantasy. Pink and blue lighting lined the platform, which was decorated with toy houses, white picket fences, carnival rides, ice cream trucks, and a giant gnome wearing a T-shirt that said "pimp."

It's been 10 years since Hilton walked at a fashion week show. Though she's modeled her own line and appeared at smaller fashion events, her last major runway was the Heatherette Spring 2007 show in September 2006, which her sister, Nicky Hilton Rothschild, was also in.
